What is the structure of the Moon, and what physical processes have

shaped its surface? In this lecture we turn to our nearest celestial

neighbor, the Moon, to see a world quite different than the dynamic

Earth. We will discuss the surface features of the Moon (the Maria

and cratered highlands), see how crater density tells us the relative

ages of terrain, and look at the composition of Moon rocks returned

by astronauts and robotic probes. We also discuss the interior

of the Moon, and review what we know about lunar history and formation.
